Basement Waterproofing

Waterproofing in Basements and Underground Car Parks

Waterproofing and drainage considerations are especially needed in cases where groundwater is likely to build up in soil and raise the water level. This higher water level causes hydrostatic pressure to be exerted underneath basement floors and against basement walls. Hydrostatic pressure forces water in through the cracks in foundation walls, through openings caused by expansion and contraction of the footing-foundation wall joint and up through floor cracks. Hydrostatic pressure can cause major structural damage to foundation walls and is likely to contribute to mould, decay and other moisture related problems.
